Let PA PB 13 and PA Union B 110 Find the following a PB b

Let P(A) = P(B) = 1/3 and P(A Union B) = 1/10. Find the following.
(a) P(B)
(b) P(A Union B’)
(c) P(B Intersection A’)
(d) P(A’ Union B’)

Solution

MATE I AM PROVINDING U THE FORMULA TO CALCULATE THE ANS AS ACCORDING TO THE DATA GIVEN ITS SEEMS THE QUESTION IS WRONG

USE THE FORMULA AND CHECK.

a) P(B) = 1/3

P(B\')= 1-1/3 = 2/3

B)

P(AB\')= P(A)+P(B\')P(AB\')= P(A)+P(B\'A\') = P(A)+1P(BA)

C)

P(BA\')= P(A) - P(AB)

D)P(A\'UB\') = P(A\') +P(B\') -P(A\'B\') ; ALSO P(A\'B\') = 1- P(AUB)

=1/3
